A confession of incest depicting the forbidden relationship between brother and sister. With their parents attending a relative's wedding, the house is empty one night. Seizing the opportunity, the siblings give in to their desires and entwine their bodies. Years of secret encounters have made them as familiar with each other's bodies as any married couple, leading to passionate, intense sex.
"Onii-chan, we did it again."
"Yeah, we've done it again... incest."
"Dad and Mom would be shocked if they found out."
"Yeah, they'd be completely horrified..."
In old Japan, such relationships between siblings were not entirely uncommon. A heartbreaking and pitiful tale where forbidden emotions and desires collide.
